These Toasted Crispy Rice Burgers with Teriyaki Mushrooms are a rice-lovers dream. These were inspired by the rice burgers from MOS burger, a Japanese fast food chain that serves rice burgers (and regular burgers as well!). I love that nice crisp form the rice buns and that satisfying bite you get from the tasty mushroom filling.
Heat a pan. Add in 1/2 tbsp oil and sauté the bell pepper. Cook until tender then set aside.
Add in the mushrooms and teriyaki sauce. Season with salt and pepper, to taste, if needed. Cook for 6-8 minutes over medium heat until mushrooms are cooked and tender. Once cooked, set aside.
Make sure your rice has been cooled. If using leftover rice that has been refrigerated and may have dried up a bit, you can splash some water and cover the rice then quickly microwave. Mix well and allow to cool for a few minutes.
Divide the 2 cups of cooked Japanese or sushi rice into 4 portions, measuring 1/2 cup each. This part will depend on the size of your buns but I used a 3-inch (diameter) round container I found and was able to make a bun that was roughly 3/4 inch thick.
Prepare the container. Place the plastic/paper/silicon wrap flat on the container. Add in the rice. Make sure it is compact. You can dip your fingers in the bowl with water to help prevent the rice from sticking to your fingers.
Flatten out the rice then wrap it well. Take it out of the mold then continue to shape the sides as needed. Repeat these steps until you have 4 round rice ‘buns’.
Heat a non-stick the pan and brush with neutral oil. Once hot, add in the rice buns. Pan fry on each side for 6-7 minutes on medium high heat until lightly browned and crisp. Brush the buns with some soy sauce or teriyaki sauce (homemade recipe here), if desired (this is just for extra flavour). Carefully flip over using a spatula and brown the other side and crush with sauce as well.
Assembling the rice burgers
Assemble the burgers by adding some lettuce, bell peppers, mushrooms, sesame seeds, and more teriyaki sauce as desired. You can also spread some vegan mayo and hot sauce if desired. Enjoy!
Storing the burgers
For leftovers or preparing these ahead, allow the burger to completely cool and then wrap the assembled burgers in some plastic wrap and place in an air-tight container to refrigerate. Make sure it’s sealed well because the rice can dry out if exposed to the cold.
MUSHROOMS AND FILLING
If you don’t have oyster mushrooms, feel free to use shiitake mushrooms or other mushrooms of choice and slice them into small strips or pieces
You can also use other filling such as tofu, plant-based meat, etc.
